For a start connect it up properly, if you don't connect 5V it can't possibly work.

Well no kidding? I had the 5V connected from the start I'm not that stupid. I was just asking if it was needed since the original parpic only supplied the 13V, but I see that the circuit was meant to supply the 5V. I just modified the parpic with a 7805 to supply it without it being "in-circuit".

Anyways maybe I should just quit being lazy and finish my tait programmer. That ones half built on a proto board and all that soldering gets old after a while. How well do tait's work?

There are many different Tait programmers, he's quite rightly the 'father of PIC programmers' - most later designs are based on his, for example, the excellent P16PRO40 is based on his standard design. However, what you should avoid is his first 'effort' that used a CMOS switch, this was a poor idea, and stems from the fact David wasn't a 'hardware guy'.
